What this shows Research's Innovation Score is 33.8/100 (46th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Research?

Each dot is one of Research’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Research’s own 13.6 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Research's grants concentrate

Research Center FOR Eco-environmental Scinces, Chinese Academy OF Sciences is a focused PatentsView assignee: 13 CPC subclasses with 77.8% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2016. By volume, Research sits between Reigstad & Associates, Inc. and Rexair LLC.

Research's three-year grant acceleration

Research Center FOR Eco-environmental Scinces, Chinese Academy OF Sciences shows 3 grants in 2022–2024 against only 4 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
